What to prepare before opening a shop
An e-commerce project almost never stalls on development. It stalls on the catalogue that is not ready, unusable photos, the distance selling contract nobody requested and the carrier account still being processed. Those four things depend on you or on third parties, not on me.
The catalogue, and nothing else, sets the timetable
On projects that slip, the cause is almost always the same: the catalogue arrives late, or arrives in a state that blocks importing. A usable catalogue fits in a spreadsheet, one row per sellable item — so one row per variant, not one per model — with stable columns: unique reference, name, description, price, VAT rate, weight, stock quantity, category, image filename.
The reference is the most important and most neglected column. It has to be unique, stable over time and identical in every other tool you use: management software, labels, stock sheets. Without it, any later catalogue update becomes manual reconciliation, and any connection to an external system becomes bespoke development.
Second trap: the description. Copy taken from the manufacturer’s site ends up identical on dozens of competing shops. It is not a punished offence, it is simply content with no reason to rank above anyone else’s. Twenty written descriptions beat a thousand copied ones.
What you will be asked for
- The catalogue as a spreadsheet, one row per sellable item, with unique references. It is the longest piece to produce and it governs everything else.
- Product images as separate files, named after the reference, at a resolution above the final display size. A small photo recovered from an old site will never become sharp again.
- The company’s legal details: name, legal form, registration number, VAT number where applicable, and the hosting provider’s details.
- Terms and conditions of sale, written for your business rather than copied. They bind you legally: this is not filler text.
- Cancellation periods, returns policy and warranty policy, matching what you will genuinely do.
- The distance selling contract with your bank, or an account opened with a payment provider, plus the supporting documents those parties require.
- Carrier accounts and, if you offer pickup points, membership of the corresponding network. These take processing time and do not speed up.
Why this order and not another
-
Third parties first, because their clock is not yours
Payment and shipping are the only items whose lead time is entirely outside your control. They start on day one of the decision, not when the site is ready to receive them.
-
The catalogue next, because it is long
Building a clean catalogue takes days of work, often weeks. That production can run while the site is being built, provided the spreadsheet format was fixed at the start.
-
Photos in parallel, with one simple rule
Always shoot larger than needed and always name after the reference. Resizing is automatic; renaming two thousand files is not, once nobody knows which file belongs to which product.
-
Legal text before launch, not after
These pages are mandatory in distance selling, and part of it must be explicitly accepted during checkout. Producing them at the last minute means copying them from elsewhere, and therefore making them inaccurate.
-
Editorial content last, but not never
Brand pages, buying guides, an about page: these are what separate a shop from a catalogue. They can arrive after opening, provided someone is tasked with writing them.
